INTRODUCTION
SAFETY WARNINGS
This book contains all the necessary fitting and operating instructions for your Unichrome Tyne thermostatic bath shower mixer.
a Layout and sizing of pipework must be such that when other services are used, pressures at the mixer control inlets do not fall below the recommended minimum.
Please read the instructions carefully. Read through the whole of this book before beginning your installation.
b Do not choose a position where the bath shower mixer could become frozen.
The mixer installation must be carried out by a suitably competent person and in sequence of this instruction book.
c Do not connect this mixer to any form of tap or fitting not recommended by the manufacturer.
Care taken during the installation will ensure a long and trouble free life from your mixer.
d The showerhead must be regularly cleaned to remove scale and debris.
For best performance within the specified running pressure range a minimum flow of eight litres per minute should be available to both inlets.
e Conveniently situated service valves in each inlet supply must be fitted as an independent method of isolating the mixer should maintenance or servicing be necessary.
The bath shower mixer must not be subjected to water temperatures above 80°C. This mixer is designed for use with high pressure systems found in the UK up to a maximum of 5 bar running pressure.
f
Important: When installing this mixer with a combination boiler or multipoint water heater a flow regulator must be installed in the unit.
If it is intended to operate the mixer in areas of hard water (above 200 ppm temporary hardness), a scale inhibitor may have to be fitted. For advice on the Triton scale inhibitor, please contact Customer Service.
g Do not operate the mixer outside the guidelines as laid out in ‘site requirements’.
The mixers are suitable for fully modulating type combination boilers and multi-point hot water heaters. It is also suitable for thermal storage and unvented systems. Important: Before installing with a gas instantaneous water heater, make sure it is capable of delivering hot water at a minimum switch-on flow rate of 3 litres per minute. At flow rates between 3 and 8 litres per minute, the appliance must be capable of raising the water temperature to a minimum of 52°C. Water temperature at the inlet to the mixer must remain relatively constant when flow rate adjustments are made (refer to the water heater operating manual to confirm compatibility with this mixer). This mixer is supplied with an integral single check valve and integral filter in each inlet. The bath pillars inlet connections are to ¾” BSP tap connector fittings (not supplied).
Replacement parts can be ordered from Triton Customer Service. See ‘spare parts’ for details and part numbers. Due to continuous improvement and updating, specification may be altered without prior notice.

site requirements
Water temperature requirements
The installation must be in accordance with Water Regulations and Bylaws.
Maximum hot water temperature = 80°C Recommended maximum = 65°C Minimum hot water temperature = 52°C
Running water pressure:
Maximum cold water temperature = 20°C
1.0 bar min. to 5.0 bar max.
BS 6700 recommends that the temperature of stored water should never exceed 65°C.
Maximum static water pressure:
A stored water temperature of 60°C is considered sufficient to meet all normal requirements and will minimise the effects of scale in hard water areas.
10 bar Do not connect the mixer to a gravity hot supply and a mains cold supply (or vice versa).
Temperature adjustment range The mixed water temperature can be adjusted from cold through to a top limit which can be preset during installation with full anti-scald protection throughout the range (35°C to 40°C) providing the hot water temperature at the inlet remains 10°C above the outlet temperature.
For optimum shower performance within the specified running pressure range a minimum flow of eight litres per minute should be available to both inlets. While the mixer is operational (open outlet), inlet pressures must not be capable of exceeding 7 bar. For effective operation of the internal seals, the maximum static pressure must not be exceeded. Note: On sites where the running pressure is above 5 bar, the use of a suitably sized pressure reducing valve fitted in the cold mains supply pipework can provide nominally equal pressures at the bath shower mixer. The pipework should be installed such that the flow is not significantly affected by taps and other appliances being operated elsewhere on the premises. Where thermal store systems and instantaneous gas water heaters are used, if excessive drawoffs take place the boiler may not be able to maintain an adequate output temperature. This could result in the shower temperature becoming noticeably cooler.

Typical suitable installations
Fig.2 (diagrammatic view – not to scale)
a) Instantaneous gas-heated systems, e.g. combination boilers (fig.2) The mixer control must be installed with a multipoint gas water heater or combination boiler of a fully modulating design (i.e. to maintain relatively stable hot water temperatures).
Combination boiler
Mixer
A drop tight pressure reducing valve must be fitted if the supply pressures exceed 5 bar running.
Service valves
An expansion vessel (shown in fig.2) must be fitted, and regularly maintained, to prevent the mixer being damaged by excess pressures. This may already be installed within the boiler (check with manufacturer) and is in addition to the normally larger central heating expansion vessel.
Hot water CH flow Expansion vessel Cold mains supply
CH return
The layout and sizing of pipework must be such that nominally equal inlet supply pressures are achieved and the effects of other draw-offs are minimised. The hot supply temperature must remain a minimum of 10°C hotter than the required blend temperature for best performance.
Stop Pressure tap reducing valve
Fig.3 (diagrammatic view – not to scale)
b) Unvented mains pressure systems (fig.3) Safety devices not shown
Mixer
The mixer control can be installed with an unvented, stored hot water cylinder. For systems with no cold water take off after the appliance reducing valve, it will be necessary to fit an additional drop tight pressure reducing valve when the mains pressure is over 5 bar. The drop tight pressure reducing valve must be set at the same value as the unvented package pressure reducing valve.

PREPARING THE MIXER VALVE
Fig.6 (diagrammatic view – not to scale)
Check the contents to make sure all parts are present. Before starting the installation, make sure all the openings on the valve are carefully covered to prevent ingress of any debris, etc. while routing the supply pipework. The bath shower valve comes supplied with fittings for installation onto a bath.
Height of showerhead to suit user’s requirement.
The hot water inlet has a red symbol next to the inlet and is on the left-hand side.
SITING OF THE BATH SHOWER MIXER
Showerhead can be mounted either side of the mixer.
WARNING! The mixer must not be positioned where it will be subject to freezing conditions. Refer to (fig.6) for correct siting of the mixer. The showerhead can be positioned either side of the mixer unit.
Installation Warning! Check there are no hidden cables or pipes before drilling holes for wall plugs. Use great care when using power tools near water. The use of a residual current device (RCD) is recommended. Note: The outlet of the bath shower mixer must not be connected to anything other than the showerhead supplied. Do not use jointing compounds on any pipe fittings for the installation. Do not solder fittings near the mixer unit as heat can transfer along the pipework and damage components. Note: Suitable service valves (complying with Water Regulations and Bylaws) must be fitted
Bath shower mixer on the hot and cold water supplies to the shower as an independent means of isolating the water supplies should maintenance or servicing be necessary.
150mm between inlet centres
Fig.7
When connecting the pipework, avoid using tight 90° elbows. Swept or formed bends will give the best performance. Important: Water Regulations require that where the showerhead can be lowered into the bath a double check valve or similar device MUST be fitted in the supply pipework to prevent back syphonage. The inlet centres on the shower valves are 150mm and the inlet centres on the bath pillars are 180mm apart (fig.7).
180mm between centres
Flush out the pipework in accordance with Water Regulations and Bylaws. Washer
Insert the left-hand side pillar into the bath top, making sure the sealing washers are in place. Secure in place with the locking nut. Repeat the process for the right-hand side pillar. Check the inlet centres are correctly aligned for the mixer valve.
Fig.8
Bath pillar Seal
Offer the mixer valve to the bath pillars and, checking the sealing washers are in place, screw the unions into the fittings. Connect pipework to the pillars using standard ¾” BSP tap connector fittings (fig.8).

Leak testing
Tap connector fitting
Fit the hose to the outlet and direct it to waste. Open the supplies and test for leaks in the valve connections. Remedy any leaks if necessary.
Fig.9
FITTING THE FIXED Showerhead HOLDER Decide the position for the showerhead holder on the wall within the bath shower area. Proceed as follows: Hold the showerhead holder mounting plate in a suitable position on the wall. Using the plate as a template, mark two locating holes (fig.9). Drill and plug the wall. (The wall plugs provided are suitable for most brick walls — use an appropriate masonry drill, but if the wall is plasterboard or a soft building block, use suitable
Bath shower mixer wall plugs and an appropriate drill bit). Fig.10
Replace the mounting plate and secure using the fixing screws supplied. Slide the showerhead holder down onto the mounting plate (fig.10) until it clicks into place.
hose and showerhead Screw the flexible hose to the shower outlet and showerhead. Make sure the supplied washers are in place at both ends of the flexible hose before fitting (fig.11). Place the showerhead into the holder and check that it fits correctly. Note: The holder is slightly tapered and the showerhead and hose will only fit from one direction. Important: It is the conical end of the hose which grips into the holder. The showerhead will not fit in the holder without the hose attached.

Commissioning
Showerhead
Shower outlet
Make sure that both hot and cold water supplies are fully open and at (or near to) their design temperature and pressures and are within the requirements as stated.
Washers
Check the temperature control (right-hand side) is rotated fully anti-clockwise to the maximum temperature setting and the showerhead is directed to waste. Start the water flow by turning the flow control (left-hand side) anti-clockwise. Allow the mixer to run at the maximum temperature setting until the water temperature has stabilised. Using the temperature control, rotate until your desired maximum showering temperature is reached. The mixer valve is fitted with a maximum temperature override button factory set at 40°C. The mixer valve is factory set to provide a maximum outlet temperature of 40°C but this should be checked on site to make sure the setting has not been altered and also to ensure user safety.
Bath shower mixer To adjust the maximum temperature override setting
Fig.12
Remove the temperature control by removing the end cap and unscrewing the retaining screw (fig.12). Turn the flow control fully anti-clockwise. With a steady flow running, adjust the temperature valve spindle (fig.13) until the temperature is about 38°C (turn right for cold and left for warm). When you are satisfied with the temperature turn off the flow control. Refit the temperature control, checking the temperature stop aligns with the reference dot on the mixer body. Secure with the screw and replace the end cap.

CLEANING
WARNING!
Do not use abrasive or solvent cleaning fluids. The shower unit, riser rail, hose, etc. should be cleaned using a soft cloth and warm water.
Do not use ‘powerful’ abrasive or solvent cleaning fluids when cleaning the shower as they may damage the plastic fittings.
Before cleaning, turn off the unit at the mains supply to avoid the shower being accidentally switched on.
Fig.16
Sprayplate key
It is important to keep the showerhead clean to maintain the performance of the shower. The hardness of the water will determine the frequency of cleaning. For example, if the shower is used every day in a very hard water area, it may be necessary to clean the showerhead on a weekly basis.
Sprayplate removal Sprayplate
There is no need to remove the showerhead from the hose. Using the removal tool supplied (fig.16), locate the raised ’bosses’ into the recesses in the sprayplate. Hold in firmly and twist anticlockwise (fig.17). This movement may turn the cartridge assembly as well until it reaches a ‘stop’.
Fig.17
Hold the cartridge firmly and continue to twist anti-clockwise. Having loosened the sprayplate, it can be unscrewed and removed completely. Clean the sprayplate with a suitable brush or preferably leave it to soak overnight in a mild proprietary descalent. Make sure all traces of scale are removed and thoroughly rinse in clean water afterwards. Before replacing the sprayplate, switch the power back on at the mains supply and direct the hose and showerhead to waste. Turn the flow control fully anti-clockwise. This operation will flush out any loose scale deposits in the unit and showerhead. Stop after about thirty seconds. Refit the sprayplate by screwing clockwise. Use the tool to screw the sprayplate tight.
